Hi. I created a replacement kernel for the Nexus 7. Together with a USB
Y-cable, this mod enables charging the N7, while running the device in
USB host mode. People are using this to operate N7 + USB DAC devices in
their cars and other things. It's a fun project.
I'm currently trying to solve an issue with slave devices not being
detectable after a sudden power loss. Slave devices will restart, when
external power comes back, but will be "not accepting address xx, error
-71". Would it make sense to try to back port some code from a newer
versions of ehci-hcd.c, including ehci_suspend() and ehci_resume(), not
existing in the 3.1.10 kernel of the N7?
Thanks a lot.
